You could try adding 'bind-interfaces' to your config, in order to
discipline your second dnsmasq instance.

Quoting from the docs:

 > On systems which support it, dnsmasq binds the wildcard address, even
when it is listening on only some interfaces. It then discards requests
that it shouldn't reply to. This has the advantage of working even when
interfaces come and go and change address. This option forces dnsmasq to
really bind only the interfaces it is listening on. About the only time
when this is useful is when running another nameserver (or another
instance of dnsmasq) on the same machine. Setting this option also
enables multiple instances of dnsmasq which provide DHCP service to run
in the same machine.


But why do you require a second dnsmasq instance?

Why wouldn't tagging allow you to manage your network with only one
instance of dnsmasq?

Kind regards,
